The reason for the difference in behavior is that for Display[], the
external program psrender is used to render the Mathematica PostScript
version of the graphic. In the case of Export[] (when a front end is
present, the kernel requests a bitmap from the front end based on what
the front end's PostScript interpreter produces.
